Baltimore plays host to 23 million tourists a year, making the tourism industry big business.

"I've been saying it's a banner year for tourism. We're already seeing a 20 percent sales uptick here in the Visitor's Center. We're seeing around an 8 percent uptick for hotel sales in the community for the first six months of the year," said Visit Baltimore president and CEO Tom Noonan.

That's why Visit Baltimore is celebrating National Tourism Week and encouraging their business members to do the same by dressing casually to raise money for a nonprofit called The Journey Home, which is the city's plan to make homelessness rare and brief.

The Visitor's Center at the Inner Harbor, which is often the hub of Baltimore's tourism industry, is also celebrating a decade of helping visitors make their trips memorable. To commemorate the anniversary, Visit Baltimore commissioned a new video that will run in the Visitor's Center to help show tourists what the city has to offer and bring in more business.

"You get this deep 10-minute immersion into Baltimore, and it's really great because we really think it's going to help sell tourists on the city. We've also developed a new two-minute long video for the mayor that's the sales pitch that goes in the front of it. What we're doing is we're bringing in all our convention sales -- when they come and do a site inspection of the city, we're bringing all of our meeting planners there, and they're getting this two-minute video from the mayor about why we're a great convention destination," Noonan said.

To the viewers, the video appears 3D with the use of cubes and a technology called cine-mapping.

"It's an immersion experience. It really takes you to a place in a theater that you don't really expect," said Cameron Uhlig of Camagine Design.

The video chronicles a brief history of Baltimore and highlights some of the things to see and do. Even people from Baltimore will enjoy coming in to check it out.

"I think they'll be impressed by their hometown. I think they're going to come in and see this video and think, 'What a great sales pitch. What a great opportunity to really show off.' When they have family and friends come into town, they can say, 'You know why I live here? Let me show you what Baltimore's all about.' They can walk into this video and see that," Noonan said.
